Published on 13 Sep 2016 by Addigy

On Sept 20th, your macOS users will be able to upgrade to Sierra, are you able to block their upgrade?

Addigy Try It

With more than a dozen major issues widely reported in Sierra throughout Beta, the most significant one found at Addigy was that our bulletproof 3.8MB agent began having runtime problems in Beta. The agent has since been tested fixed and already fully deployed in production. The 10.12 macOS Sierra build has changed certain core system calls, which required major changes to our the Addigy agent, and many other companies including Facebook and others have been reporting problems due to the significance of these system calls. Apple macOS users with admin rights have the power to upgrade their machine to Sierra, and 70% of them will eventually do so because it’s also FREE! Even when you decide to upgrade, we highly recommend orchestrating and monitoring TimeMachine backups with Addigy before pushing the upgrade out.

The question to ask is if the new Siri feature in macOS Sierra takes priority over ensuring you don’t have any whiplash of issuesexplained below… To guard against this, Addigy has provided a simple process to block macOS Sierra from being installed. Simply add the following Software item to a given policy of Machines:
